1 INTRODUCTION
In July 2020 the Joint Video Experts Team (JVET), a collaborative project of the ITU-T Video Coding
Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG), has finalized a new
video coding standard called Versatile Video Coding (VVC) [1]. VVC is the successor of the High
Efficiency Video Coding (HEVC) standard [2] and will be released by ITU-T as H.266 and by ISO/IEC
as MPEG-I Part 3 (ISO/IEC 23090-3). The new standard targets a 50% bit-rate reduction over
HEVC at the same visual quality. In addition, VVC proves to be truly versatile by including tools
for efficient coding of video content in emerging applications, e.g. high dynamic range (HDR),
adaptive streaming, computer generated content as well as immersive applications like 360
degree video and augmented reality (AR).
The VVC test model (VTM) [3] serves as a common reference implementation, i.e. a test bed for
evaluation and verification of proposed technologies during standardization. While VTM used to
be the only publicly available encoder and decoder implementation of the VVC standard, it is
aimed at correctness, completeness and readability and should not serve as a real-world example
of an VVC encoder and decoder.
The Fraunhofer Versatile Video Encoder (VVenC) development was initiated to provide a publicly
available, fast and efficient VVC encoder implementation. The VVenC software is based on VTM,
with optimizations including software redesign to mitigate performance bottlenecks, extensive
SIMD optimizations, improved encoder search algorithms and basic multi-threading support to
exploit parallelization. Additionally, VVenC supports real-world encoder features, including
frame-level rate control and perceptually optimized encoding in order to provide a flexible, fast
and easy to use video encoding solution for the VVC standard.
Bit-streams encoded with VVenC can be decoded by any VVC standard compliant decoder, e.g.
the VTM-10.0 reference software decoder. Alternatively, the fast Fraunhofer Versatile Video
Decoder (VVdeC) solution can be used [4].
Features at a Glance
§ Easy to use encoder implementation with four predefined quality/speed presets.
§ Optimized VVC encoder providing speedups between 22x and 270x over VTM-10.0 for
HD and UHD test sequences depending on the chosen quality/speed preset.
§ Perceptual optimization to improve subjective video quality.
§ Frame-level rate control supporting VBR encoding.
§ Expert mode encoder interface available, allowing fine-grained control of the encoding
process.
